Your opponent, in a desperate attempt to return your wicked serve, makes a high lob of the tennis ball that causes it to land out of bounds on the asphalt course behind you. It then bounces so that it just barely clears a 3.52 m wall that is 2.22 m from where the ball hit the asphalt and that is separating your court from the next. In the adjacent court play is suddenly interrupted by the ball leaving your court and bouncing 1.82 m up into the action. How far horizontally, in meters, does the ball travel in this second bounce? Hint: Use the trajectory of the first bounce to get the horizontal speed, and assume that it remains unchanged between bounces
